| Criterion | Weight | What good looks like | What weak evidence looks like | Test or artefact to request |
|---|---|---|---|---|
| Scope completeness and correct uncertainty | 20 | Expected obligations reconciled; ambiguity escalated; critical cases pass | Only returned fields are counted; missing pages ignored | Reference-output comparison and omissions log |
| Source traceability and reviewer usability | 15 | Material findings link to precise, correct source regions; corrections are efficient | Polished output with whole-folder links | Reviewer completes a source-check exercise |
| Net estimator effort | 15 | Comparable timing includes preparation, checking, fixes and maintenance | “Seconds to process” presented as hours saved | Paired/comparable trial log with denominator |
| Addenda and revision control | 10 | Changes, deletions and superseded values stay visible | New file overwrites evidence; changed tags disappear | Deliberately revised tender case |
| Pricing, units and labour controls | 10 | Dated approved inputs, explicit matching and controlled overrides | List price treated as a negotiated offer; silent conversions | Stale-offer, unit and margin-exception cases |
| Security and data handling | 10 | Authorised data path, access, deletion and incident responsibilities | Cloud brand used in place of application evidence | Data-flow review and deletion/access test |
| Integration and recovery | 7 | Identifiers preserved; retries and reconciliation work | Demonstration only covers a successful transfer | Sandbox fault tests and field-ownership map |
| Operations, support and change testing | 5 | Named owner, fallback and regression process | One developer holds undocumented knowledge | Support runbook and change exercise |
| Complete cost and commercial clarity | 5 | Comparable three-year scope with explicit unknowns and dependencies | Cheap prototype omits delivery obligations | Normalised proposal and acceptance/payment schedule |
| Exit and portability | 3 | Usable exports, configuration and appropriate custom-work rights | PDF-only output or unpriced exit | Export/rebuild exercise and contract clauses |
| Total | 100 |
These weights deliberately prioritise scope and reviewability over the headline licence price. Change them only before trials, with a recorded reason tied to the buyer's situation.
